Testosterone Cypionate is simply Testosterone with the Cypionate ester bound to the Testosterone chemical structure. ‘Cypionate’ is Cypionic acid, but once bound to Testosterone it is known in chemistry as an ester bond. When Testosterone Cypionate enters the body, enzymes will bind to the molecule and break down the bond between the ester and the Testosterone hormone, which takes some time depending on the size of the ester in question. Esters such as Cypionate, Enanthate, Decanoate, Undecylenate and so forth all possess longer half-lives than the smaller and shorter esters such as Propionate, Phenylpropionate, Acetate, etc. The process of enzymes breaking down and separating the ester from the Testosterone molecule results in the slower drug release profile. Pure Testosterone base with no ester bonded to it has a half-life of approximately 2 – 4 hours. With a Cypionate ester attached to it, the half-life is now extended to 12-14 days
